Diablo 3 declared 'fastest selling PC game' ever

Blizzard has declared Diablo III the fastest-selling PC game of all time, selling 3.5 million copies within the first 24 hours, and boasting over 6.3 million players within the week.

From the launch day server meltdown to the way everyone you know seems to be playing, it's pretty clear that Diablo III is quite popular. But just how popular? Blizzard announced today that it sold 3.5 million copies within the first 24 hours, which supposedly makes it the fastest-selling PC game of all time.

On top of those 3.5 million copies were another 1.2 million doled out free to World of Warcraft Annual Pass subscribers. After a week, Blizzard says, Diablo III was up to 6.3 million players--not including South Korean game rooms, where it's estimated to have a 39% share.

"We're definitely thrilled that so many people around the world were excited to pick up their copy of Diablo III and jump in the moment it went live," CEO Mike Morhaime said in the announcement.

"We also regret that our preparations were not enough to ensure everyone had a seamless experience when they did so. I want to reaffirm our commitment to make sure the millions of Diablo III players out there have a great experience with the game moving forward, and I also want to thank them for their ongoing support."

As well as rolling out sneaky little balance updates, Blizzard is investigating reports of nasty hacks, and preparing to launch the real-money auction house on May 29.
